UNETED STATELd a e wax 4 r it earner a GAUGE FOR SIAPLING MACHINES.

Application filed September To all whom it may concern:

Be it known that I, J OHN W. \VsLoi-i. acitizen of the United States, residing at i-itlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Gauges for stapling Machines, of which the following is a specification.

My invention relates to adjustable gauges tor stapling or stitching machines, or. the like.

An important object of the invention is to provide a device of the above mentioned character which will position the leaves of a pamphlet being stitched, with respect to the stapling mechanism and which will also gauge the distance that the cover should overlap the leaves or body the pamphlet.

Another object of the invention is to provide a device of this character which can be attached to any machine of this kind now in use without the exercise of any great mechanical skill or labor.

Another object of the invention is the provision of a device of the above mentioned character, which is simple of construction, cheap and eas: to manufacture, is strong and durable.

Qther objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like 'parts throughout the same,

Figure 1 is a front elevation of a saddle equipped with my device,

Figure 2 is a rear elevation 01" the same,

Figure 3 is a transverse sectional View taken on line of Figure 2 and looking in the direction of the arrows,

Figure 4k is a perspective view of the gauge members, and,

Figure 5 is a fragmentary view showing the device in use and associated with a pamphlet being stitched.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral designates the saddle of the stitching machine, which is of the usual construction, and which is of an inverted V-shape in cross sec tion, the front and rear sides or sections of which are designated at 11 and 12 respectively. The usual staple clencher or anvil block 13 is arranged in about the center 01 1923. lierial No. 660,928.

the saddle, as is usual, and the stitching mechanism, (not shown) would be arranged directly above the staple clencher.

My improved gauge comprises two sections, a base section 1 1 and top section15, which are inverted, ii-shaped in cross section and which have their side sections arranged at the same angle to each other as the side sections of the saddle. T he rear section 16 of the base member 1a is provided with a longitudinally extending slot 17, and the rear section 18 01" the top member is provided with a corresponding slot 19. The members 1% and 15 are adapted to fit one above the other in which position the slots 17 and 19 will coincide. These gauge members rest on the apex of the saddle and a thumb bolt 20 passes through the slots 17 and 19 and through the rear section 12 of the saddle and carries a nut 21 which bears against the under side oi the rear saddle section 12.

The under or base section 1; is provided with a scale or graduation 22 which indicates the distance the top section 15 is moved with respect to the base section 1%.

In operation, the body 23 of the pamphlet, or the like, to be stitched is placed on the saddle, the thumb bolt 20 is loosened and the base section slid up to engage the body 23 of the pamphlet, and when the body 23 is positioned with respect to the stapling mechanism, the base section 1% serves as a guide or gauge. shifted with respect to the base section the distance that it is desired to have the cover 24; overlap the body 23, which distance is indicated on the scale 22. The thumb bolt is then tightened and the gauge may be used for any number of pamphlets.

lVith this arrangement only two stitches are necessary in place of the three usually used, and a great saving of labor and time is possible. i

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred embodiment of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claims.

Having thus described my invention, what I claim is:

1. The combination with a saddle of a machine for stapling or stitching pamphlets The top section 15 is.

ill

or the like, of a gauge comprising a base sec tion which is inverted V-shaped in cross section and which has a longitudinally extending slot in one of its sides, a top section of inverted V-shape in cross section, said top section being adapted to fit over the base section and being provided with a corre sponding longitudinally extending slot, means to clamp the gauge sections to the saddle whereby the base section is longitudinally adjustable with respect to the saddle and adapted to position the leaves or body of the pamphlet to be stitched with respect to the stitching mechanism and the top section is adjustable with respect to the base section and adapted to position the cover of the pamphlet with respect to the body thereof, and a'scale carried by the base section, whereby the edge of the top section serves '2 as an indicator or marker.

2. The combination with the saddle oi a machine for stapling or stitching pamphlets or the like, of 'a gauge comprising a base section which is inverted V-shaped in cross section and which has a longitudinally extending slot in one of its sides, a top section of inverted V-shape in cross section, said top' section being adapted to fit over the base section and being provided with a corresponding longitudinally extending slot, and means to clamp the gauge sections to the saddle whereby the base section is longitudi nally adjustable withrespect to the saddle and adapted to position the leaves or body of the pamphlet to be stitched with respect to the stitching mechanism and the top section is adjustable with respect to the base section and adapted to position the eoveroit' the pamphlet with respect to the body thereof.

In testimony whereof I atiiX my signature.

JOHN W. WELCH.
